  • •When cleaning up messy audio filenames by removing unwanted text, adding prefixes, or converting cases to title or lowercase.
  • •When preparing voiceover files or sound effects for game development and video editing projects that require strict naming conventions.

How It Works

  • •Upload up to 50 audio files that you want to rename.
  • •Define your renaming pattern using placeholders like {name} and {n:03}, or set up text replacement, prefixes, suffixes, and case conversion.
  • •Click the rename button to process your files and download the renamed audio tracks packaged in a single ZIP file.

Use Cases

Formatting raw podcast recordings into structured episodes with sequential numbering like 'Episode_001_Intro'.
Standardizing sound effect libraries by adding prefixes like 'SFX_' and converting all filenames to lowercase.
Cleaning up downloaded music tracks by replacing unwanted characters and applying Title Case formatting.

Examples

1. Sequential Track Numbering for Music Albums

Independent Musician
Background
An artist has finished recording a 10-track album, but the exported audio files have inconsistent, messy names from the DAW.
Problem
The artist needs to format the tracks sequentially with zero-padded numbers and a clean album prefix.
How to Use
Upload the 10 audio files, set the Rename Pattern to 'Album_Track_{n:03}', and set the Start Number to 1.
Example Config
Rename Pattern: Album_Track_{n:03}, Start Number: 1
Outcome
The files are renamed to 'Album_Track_001.mp3', 'Album_Track_002.mp3', etc., and downloaded in a ZIP archive.

2. Standardizing Sound Effects for Game Development

Sound Designer
Background
A sound designer has a batch of raw explosion sound effects named 'exp_1_raw.wav' and 'exp_2_raw.wav' that need to match a project's naming convention.
Problem
The designer needs to add a standard prefix, remove the '_raw' suffix, and convert the names to uppercase.
How to Use
Upload the WAV files, set Find Text to '_raw', leave Replace With empty, add the Prefix 'SFX_', and set Case Conversion to UPPERCASE.
Example Config
Find Text: _raw, Replace With: (empty), Add Prefix: SFX_, Case Conversion: UPPERCASE
Outcome
The files are renamed to 'SFX_EXP_1.WAV', 'SFX_EXP_2.WAV', and delivered in a ZIP file.
